Sister Teresa Katherine Cheslock

She had earned three science-related degrees, including a PhD in Human Nutrition from the University of Wisconsin, Sister began ministry as a high school science teacher at the former Fontbonne Academy in Bethel Park where she taught from 1967-74. Affectionately known as “Sister T.K.,” Sr. Teresa Katherine has been described as a gifted, caring teacher and inspiring mentor to students whom she encouraged to fully develop their skills and talents.

Sr. Teresa Katherine later served as a Director of Religious Education at St. Paul Parish in Butler (1974-1980) and Immaculate Conception Parish in Washington, Pa. (1980-1997). For the next 24 years, Sister served in pastoral ministry in Canonsburg, Pa., and then retired to the Motherhouse.

When the Diocese of Pittsburgh asked parishes to implement a “faith revitalization program” in 1989, Sister already had begun several years of groundwork for spiritual renewal at Immaculate Conception, one of the first parishes to respond to the mandate. She tapped into the energy of the Adult Education Committee, organizing more than 30 weekly Bible study and contemplative prayer groups. Sister will be remembered for her gentleness, intellectual curiosity and deep respect for nature.
